Abstract. This paper represents an additional contribution toward the knowledge of a bryophyte flora of Chapada Diamantina National Park in the State of Bahia, Brazil, in which are reported 27 species of mosses belonging to 22 genera and 14 families, and four species of liverworts belonging to four genera and three families. Most of these species seem to be restricted to this high altitude geomorphological complex area.

Abstract: Three species of Webera and Pohlia described from China were reduced to new synonyms of other species of Pohlia. Webera ciliifera Broth. is a synonym of Pohlia elongata Hedw., W. pygmaea Broth. is a synonym of P. minor Schleich. ex Schwaegr. and P. subflexuosa Broth. is a synonym of P. flexuosa Hook.

Diversität epiphytischer Moose eines westandinen Bergregenwaldes in Ecuador

Ute Müller & Jan-Peter Frahm

Botanisches Institut der Universität Bonn, Meckenheimer Allee 170, D 53115 Bonn

Abstract: The epiphytic bryophytes on tree trunks as well on branches and twigs of the canopy were studied in a montane rain forest in the Andes 110 km SW of Quito at about 2000 m elevation. Ten trees were examined on which 65 species (24 mooses and 41 liverworts) were found. The bryophyte flora of the stems consists of 14 species and is related on a level of up to 80%. The branches are inhabited by 58 species. The composition of species on branches of different trees (except those from the same trees) have a correspondence of less than 40%. The correspondence of the bryophytes on twigs of different trees is even lower. Twigs are inhabited by 24 species. Correlation analysis between species numbers and ecological factors revealed no significant correlation between species number and branch diameter, branch exposition and elevation. However, a correlation was found between increasing pH of the bark and decreasing species numbers. The average dry weight of epiphytic bryophytes was 80g/m2 on trunks, 1873 g/m2 on branches and 1230 g/m2 on twigs. The average water storing capacity of epiphytic bryophytes is 0.57 l/m2 on trunks, 19,5l/m2 on branches and 4.16 l/m2 on twigs and is thus ten times of the dry weight on branches but three times of dry weight on twigs. A representative tree of 27 m height has an average 65,4 kg dry weight of epiphytic bryophytes, which can store 669 liters of water. 10600 kg phytomass per hectare are estimated.

Foliicolous lichens and their lichenicolous fungi collected during the Smithsonian International Cryptogamic Expedition to Guyana 1996

Abstract: A total of 233 foliicolous lichen species and 18 lichenicolous fungi are reported from Guyana as a result of the Smithsonian "International Cryptogamic Expedition to Guyana" 1996. Three lichens and two lichenicolous fungi are new to science: Arthonia grubei sp.n., Badimia subelegans sp.n., Calopadia pauciseptata sp.n., Opegrapha matzeri sp.n. (lichenicolous on Amazonomyces sprucei), and Pyrenidium santessonii sp.n. (lichenicolous on Bacidia psychotriae). The new combination Strigula janeirensis (Bas.: Phylloporina janeirensis; syn.: Raciborskiella janeirensis) is proposed. Apart from Amazonomyces sprucei and Bacidia psychotriae, Arthonia lecythidicola (with the lichenicolous A. pseudopegraphina) and Byssolecania deplanata (with the lichenicolous Opegrapha cf. kalbii) are reported as new hosts for lichenicolous fungi. Arthonia pseudopegraphina growing on A. lecythidicola is the first known case of adelphoparasitism at generic level in foliicolous Arthonia. Arthonia flavoverrucosa, Badimia polillensis, and Byssoloma vezdanum are new records for the Neotropics, and 115 species are new for Guyana, resulting in a total of c. 280 genuine foliicolous species reported for that country, while Porina applanata and P. verruculosa are excluded from its flora. The foliicolous lichen flora of Guyana is representative for the Guianas (Guyana, Suriname, French Guiana) and has great affinities with the Amazon region, while the degree of endemism is low. A characteristic species for this area is Amazonomyces sprucei. Species composition is typical of Neotropical lowland to submontane humid forests, with a dominance of the genera Porina, Strigula, and Mazosia. The table mountain vegetation supports elements of the upper montane forest, such as Echinoplaca fusconitida and Logilvia gilva. Foliicolous lichen diversity is highest in undisturbed lowland to submontane humid forest, much lower in the table mountain vegetation and drastically decreased in semi-open secondary vegetation and the coastal savanna. Species composition in semi-open, disturbed vegetation is similar to that found in the undisturbed forest canopy. Site preferences of foliicolous lichens follow those established by studies in other Neotropical regions like Costa Rica.

Abstract: Three genera of the moss family Sematophyllaceae are revised for Africa as part of a project looking at the mosses of Seychelles. Two of the three species of the genus Rhaphidostichum Fleisch. (Sematophyllaceae, Bryopsida) prove to belong to different genera (Papillidiopsis (Broth.) Buck & Tan and Acroporium Mitt.). One of the two species of Warburgiella Fleisch. is shown to belong to Trichosteleum All species are described and illustrated. The following two new combinations are made: Papillidiopsis mahensis (Besch.) O’Shea (basionym Rhaphidostegium mahense Besch.) and Acroporium subluxurians (Dix. & Thér.) Tan & O’Shea (basionym Rhaphidostichum subluxurians Dix. & Thér.). Papillidiopsis malayana (Dix.) Tan is made a synonym of P. mahensis, and the basionym of Warburgiella leptorrhyncha is altered to Hypnum leptorrhynchum Müll. Hal., Synopsis 2: 313. 1851.

Abstract: A survey of the limited literature on the mosses of Belize and an examination of various taxonomic revisions has been made, together with many recent collections giving rise to a list of 250 species and 13 varieties. Extensive nomenclatural changes have been made since the older contributions came into print, so that the present list will serve as a basis for future recording
